    I think it is Primus gas stove Express Spider, and a varyfuelpump also by primus.
    please see www.primus.eu

    You seem to have the tiny rectangular pre-heating pan on it. I am not sure if that is original or added later. Primus had (have?) multifuel kits for converting cannister stoves to liquid fuel (you have the pump as well). Next step will be looking at the jet, there are different propane (cannister) / white gas / kerosene jets.

    All the best, e

    It has a 28 jet. White gas?

    For safety I will use kerosene.

    The fuel does not flow well. Kerosene will not get hot. I have disassembled and cleaned with carb cleaner. I even tried without the cable.
    No more time, I had to quit.
    Is this the Lander?

    On my phone. More later.

    Hi @snwcmpr
    Yes, i have been tinkering with similar stoves, and they will not burn kerosene well. White gas should be OK. I think the instructions say kerosene is “in an emergency”. I had the same experience as you describe, needed to use a torch for extra pre heating to get the kerosene going.

    I am not at home right now, and I do not quite remember, the jet sizes. In general kerosene has the smallest aperture, then white gas a bit larger and propane/cannister the largest.

    The jets for my Omnifuel are 0.28 0.37 0.45 and that one will also burn kerosene by the way. The Omnifuel is a more powerful stove so the jets are not directly comparable to yours.

    I am pretty sure the jet in my ETA stove - that is a cannister stove almost identical to yours - is 0.32.

    0.28 for white gas sounds right, but I am not 100% sure. Need to find the instructions to check.

    I am also pretty sure the information is here on CCS, so somebody might be able to pitch in.

    All the best, e

    This stuck on my brain, so I found a Primus MultiFuel instruction online. Look in the upper left corner

    It says
    0.28 0.32 0.37 then a bit below it says
    0.28 0.37 0.45 go figure

    I think you need to test what fuel goes with your stove. I am also pretty sure the jet can be bought somewhere, all though I am not exactly sure where/how. e

    I had leaks, so until I fix that I will not use gas.

    Thanks
